Abstract

The translucent display screen on which information may be displayed is especially for cathode ray tubes in which the image is projected from behind the screen. The screen has a microgrid. The grid is obtained by printing or by bonding a thin layer with a photo printed grid. It provides a clear display and cancels any outside light reflection. It can easily be cleaned and is not susceptible to wear.
